We demonstrate chip-scale flat-top filters at near-infrared wavelengths using negative index photonic crystal based Mach Zehnder interferometers. We further show that our approach can be used to design multi-level tunable filters.
In this paper, the development of a water bath control system in a virtual laboratory environment is discussed. The system proposed is developed using LABVIEW 8.6. This project consists of three stages. The first stage is hardware development, which involves construction of interface circuit to allow communication between plant and computer. The second stage is to build the Fuzzy Logic Controller...
We demonstrate zero phase delay and deterministically tunable zero-n bandgaps in path-averaged zero-index photonic crystal superlattices. Phase differences are measured with integrated Mach-Zehnder interferometers and all measurements agree well with theoretical analysis and simulations.
We demonstrate 10-Gb/s optical data channels through broadband hitless switches, with open eye-diagrams and error-free operation (BERs less than 10-12). Both through- and drop-ports are measured in the hitless operation for transparent chip-scale optical networks.
